BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention is in the technical field of electricity generation and pertains more particularly to methods and apparatus for generating electricity from wave motion.
2. Description of Related Art
It is well known that electric generation by burning fossil fuels releases carbon into the Earth's atmosphere in gaseous forms. This circumstance, along with other situations releasing carbon into the atmosphere has resulted in demonstrable global warming.
It is also well known that to reduce or eliminate global warming it is necessary to generate electricity from renewable sources like solar and wind energy, and both of these sources have been aggressively exploited. Another renewable source that has not been exploited to such an extent is wave energy. Apparatus is known that may be used in flowing water, such as a river or spill from a dam, and also in current induced by changes in tides, but such apparatus requires that there be continuing current in one direction. Waves do not produce such a current.
What is needed in the art is apparatus that may harness the changing motion of water in wave phenomenon.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of an apparatus 100 comprising a wheel 101 with extending paddles 102 useful for driving a turbine in the prior art. In this example wheel 101 turns on an axis of a shaft 103, the shaft supported by two vertical supports 104. In one implementation the wheel may be a stator and the shaft a stator of an electric generator. In another implementation shaft 103 may rotate from torque provided by the wheel and the rotating shaft may be harnessed with gearing apparatus to turn an electric generator.
It will be apparent to the skilled person that if the entire wheel with paddles is totally immersed in water, either still or in moving current, the wheel will not turn. In use such an apparatus, sometimes termed a paddle wheel, is positioned with just the paddles on a lower extremity immersed in a flowing current, which causes the wheel to rotate. Such paddle wheels are also used as mill wheels with falling water hitting the paddles on one side, turning the wheel.
FIG. 2 is a perspective view of an apparatus 200 with a wheel 201 useful for converting wave motion in an embodiment of the invention. Wheel 201 has a plurality of buckets 202 spaced around the periphery of the wheel, with open faces of the buckets facing in a direction tangent to a rim of the wheel. The wheel, as in FIG. 1 , turns on a axis 203 supported by vertical supports 204 in this example.
It is well known that wave motion differs from liquid current in that the motion of a wave is repetitive upward and downward motion of the water. It may be seen that with apparatus 200 in a vertical aspect as shown, a bucket on one side of wheel 201 faces down and the corresponding bucket on the other side faces upward. It will be apparent to the skilled person that if apparatus 200 is immersed completely under water in a location where there is significant wave motion, as a wave rises the water motion will effect the buckets on one side facing down more strongly than the buckets on the other side of the wheel facing upward. Then as the wave falls the water motion will effect the buckets facing upward more strongly than the buckets facing down. So the wave motion, either rising or falling, will tend to turn the wheel in the same direction providing torque at the axis 203.
FIG. 3 is a perspective view of an apparatus 300 in in embodiment of the invention to maximize torque and efficiency in converting wave motion to rotary energy that may be harnesses to create electricity. Apparatus 300 comprises a vertically oriented conveyor belt 301 operating around a plurality of geared rollers 303 with shafts 304 extending from both ends of each gear wheel. Conveyor belt 301 has a plurality of extended buckets 302 oriented across the width of the conveyor belt and spaced along the length of the conveyor belt. The long buckets 302 are joined to the conveyor belt such that the openings to the buckets all face in the same direction, so the buckets face upward on one side of the conveyor belt and downward on the other side. This circumstance follows the purpose of apparatus 200 of FIG. 2 . Immersed in water with wave action, the wave action either upward or downward will urge the conveyor belt in the same direction and turn the plurality of geared rollers 303 always in the same rotary direction, which will turn the shafts 304 all in the same rotary direction. Shafts 304 may be used to drive generators through geared mechanisms not shown to produce electricity.
FIG. 4 is a perspective view of a self-contained wave energy generating unit 400 in an embodiment of the invention. Unit 400 has a sealed cabinet 401 with two opposite portions 402 a and 402 b and a conveyor belt apparatus 300 integrated between the opposite portions of the cabinets. Shafts 304 from each end of each of the gear units within the conveyor belt pass into portions 402 a and 402 b through sealed openings and connect within the sealed housings to electrical generators (not shown). Hooks 403 are for lifting and placing generating unit 400 to be immersed. Waves operate on the buckets of the conveyor belt, turning the gear wheels which turn generators, which may be through a gear train, and electricity is generated. Wiring carrying generated current from the generating unit 400 is not shown.
FIG. 5 is a partially cutaway view of an enclosure 500 which represents one portion of enclosure 401 of FIG. 4 . One generator 501 with shaft is shown in the enclosure connected to a gear 505 driven by a larger gear 504 that is driven through a sealed opening by shaft 503 by one roller 502. Roller 502 represents one roller 303 as shown in FIG. 2 in conveyor belt 301. Shaft 503 in FIG. 5 represents one shaft 304 from FIG. 3 and FIG. 4 . As wave motion drives conveyor belt 301 shaft 503 turns gear 504 that turns gear 505 that drives the generator. In the finished unit a plurality of rollers 303 drive a plurality of generators on both sides of the conveyor belt.
In operation there is thought to be a small time period wherein the motion of the water transitions from downward to upward in a wave. The inventor has provided an addition driving force that helps the conveyor to keep moving during this short period. FIG. 6 illustrates a wind driven air pump 601 having a shaft 602 with wind vanes 603 a, 603 b and 603 c. Wind turns shaft 602 and the air pump delivers air via a line 604 to a distribution lines proximate conveyor 300. The distribution lines deliver the air into the extended buckets 302 on the side of the conveyor where the buckets face downward. The air provides a motive force to the buckets to help drive the conveyor. Structure 605 represents structure connecting to sealed cabinet 401.
The skilled person will understand that the embodiment illustrated and described above are exemplary only and not limiting to the scope of the invention. There are many alterations that may be made in the embodiments described within the scope of the invention. The scope of the invention is limited only by the claims.
